1.A window washer weighing 771.1 N is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 299.4 N and is 4.727 m long. What is the force in each rope when the window washer stands 1.4 m from one end?

1.1. Force in Rope 1 (Rope closest to the window washer.)=

1.2. Force in Rope 2 (Rope farthest from the window washer.)=

3.1. M, a solid cylinder (M=1.63 kg, R=0.111 m) pivots on a thin, fixed, frictionless bearing. A string wrapped around the cylinder pulls downward with a force F which equals the weight of a 0.570 kg mass, i.e., F = 5.592 N. Calculate the angular acceleration of the cylinder.

3.2. If instead of the force F an actual mass m = 0.570 kg is hung from the string, find the angular acceleration of the cylinder.

3.3. How far does m travel downward between 0.690 s and 0.890 s after the motion begins?

3.4. The cylinder is changed to one with the same mass and radius, but a different moment of inertia. Starting from rest, the mass now moves a distance 0.347 m in a time of 0.450 s. Find Icm of the new cylinder.

A pulley with mass Mp and a radius Ro is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot. T3 Mp T2 M2 T1 m1 Mass M2 is larger than mass m1. The quantities Tn and g are magnitudes. T3 is ..... mig + M2g + Mpg. T2 is ..... T1; The magnitude of the acceleration of My is ..... that of m1. True T1+ Tzis ..... T3 False Greater than T1 is ..... mig. Less than The C.M. of Mp+M1+M2 accelerates. Equal toA 28.7 kg block (m1) is on a horizontal surface, connected to a 6.90 kg block (m2) by a massless string as shown in the Figure below. The frictionless puiiey has a radius R = 0.081 m and a moment of inertia I=0.120 i
